Abstract
Technologies for 3D printing digital rights management (DRM) include a 3D printing device communicatively coupled with a 3D model storage server and a rights management server over a network. The 3D printing device may establish a model unlock engine in a first trusted execution environment and a key release engine in a second trusted execution environment. The model unlock engine may extract a content access policy and a content key from an encrypted 3D model and generate a content key request to the key release engine. The key release engine may validate the content key request and decrypt the content key in response to the content access policy being satisfied. The model unlock engine may further decrypt 3D model content included in the 3D model using the decrypted content key to facilitate the printing of the 3D model.
